Hi people,
and thanks so much for this amazing creation!

I've been trying to import model libraries from various sources including the ones on http://www.sweethome3d.com/importModels.jsp#ModelsLibraries.

After selecting a .zip I soon get a message saying library was successfully imported and new models can be found in the catalog, which indeed seems to refresh.

However, not a single new object actually shows up in the catalog.

some more info:
* If I try importing the same zip again, I get a msg saying that the library already exist..!
* I tried zipping together some zips not in my catalog yet, and importing as library - exact same behavior as above, on first and subsequent attempts.
* Then I load each of those models (zip=obj+mtl) separately with import wizard and all new models show up perfectly!
* The successful-unsuccessful importing of libraries never asks me for their category or anything else - is this OK?
* The "import furniture library" dialog initially masks "Furniture Libraries" only, so I switch to "All Files" and select a .zip - is this OK?
* I am not quite sure whether all objects now visible in my catalog are the ones that came with sh3d installation, or whether an import of libraries did work until a certain stage.
* Shutting & restarting all instances of sh3d does not change the problem.
